Positioning device

Abstract

Abstract PURPOSE:To position the stop of a moving material simply and surely, by causing gaps between address set plates, which are fitted to a guide rail, and an address detector to differ from one another by address and by addressing them by frequencies different from one another by address. CONSTITUTION:A moving material 1 runs along a guide rail 2. The guide rail 2 is provided with address set plates 3-1, 3-2-3-n which set addresses of the stop point and stop point set plates 4-1, 4-2-4-n. The moving material 1 is provided with an address detector 5 and a stop point detector 6. The address detector 5 is provided with an inductance where a coil is wound around both legs of a channel-shaped core; and if gaps for address set plates 3-1, 3-2-3-n are made different from one another, the inductance is changed for every address, and the oscillation frequency is changed, and thus, addresses are detected easily.
